DISTRIBUTION OF PT&ROPUS
The inner margin of the nostrils projects, a preparation for the
tubular nostrils of Harpyia* The tail is absent. The pre-
molars are three and the molars two. The pyloric region of the
stomach is extended, and twisted upon itself. Of this genus
there are nearly sixty species^ extending from Madagascar to
Queensland. Thirty species inhabit the Australian, twenty the
Oriental region. Madagascar has seven, and one species just
enters the Palaearctic. The occurrence of this genus in India
and in Madagascar is one of those facts which favour the view
supported, on these and other grounds, by Dr. Dobson and J3r.
Blanford that a connexion between India and Madagascar must
once have existed ; for these slow-flying creatures could hardly
be believed capable of traversing vast stretches of ocean by
their unaided efforts.1
Pteropus is represented in the Ethiopian region by the allied
genus J^pomopfaorus. Of this there are perhaps a dozen species.
